1. The valve low pressure air tightness test stand consists of 6 channels, the inlet input air source pressure is 15 MPa, and the compressed air output is 6 channels. The pressures are: 0-0.06MPa, 0-0.25MPa, 0-0.6MPa, 0-1.6MPa, 0-4.0MPa, 0-10MPa. The deflation pipeline is 1 channel (6 channels output integrated 1 channel deflation), the test pressure can be outputed in two ways, independently and combinedly.

2. System working pressure≤15MPa, navigation mark 37° inner cone, air source inlet diameter ≥8mm, test system pressure pipeline diameter ≥6mm.

3. The inlet and outlet of the system are all equipped with filters, the inlet filtration precision is not less than 10um, the outlet filtration precision is not less than 5μm; the inlet and outlet are all equipped with mechanical pressure gauges.
